EXPEGTOB-ATING DEVICE FOR VEHICLES.

Application filed January 2, 1925. Serial No. 290.

To all whom t may concern.'

` stumps, peanut shells etc., out? of the vehicle.

A` further object is to provide cach such aperture with a slide normally closing same but readily moved to provide an opening.

It is obvious that the device will dispense with the objectionable use of cuspidors or the equally objectionable conditions making it necessary to open Vvehiclel windows to throw out any waste matter. The latter condition is'of course particularly aggravated in wintry or rainy weather when the vehicle windows are usually closed.

f I have illustrated my device in its simplest and most effective Vform and mainly in unobstructive position under the floor of a railway vehicle and the manipulated parts adjacent a seat of the vehicle.

In the accompanying drawing,-

Fig. 1 is a floor plan or top view of a portion of a railway coach and one of my devices installed near one ofits seats.

Fig. 2 is an enlargedsectional elevation about as on line 2-2 in Fig. 1.

Fig. 3 is a top view of my device with the rotating rod 22 cut od about as on line 3,-8 in Fig. 2.-

Fig. 4 is vertical sectional view about as on line 44 in Fig. 2.

Fig. 5 is an enlarged sectional view on line 5 5 in Fig. 4.

Fig. 6 is an enlarged sectional View of the shutter plate and adjacent parts as on line 6 6 in Fig. 1.'

Referring to the drawing by reference numerals, Fig. 1 shows a portion of a passenger carrying vehicle inwhich 10 is the floor, 11 a side wall with windows 12, seats 13 fixed near said windows and having each the usual arm rest 14. 15 is a preferably rectangular opening in the iioor and 16 is a metal guard about said opening andsul'ed to the door with Yscrews 16a. Said' guard may be set 4flush with the top of the floor as shown in Fig. 6.

17 is a quadrangular plate arranged to normally close the Hoor opening and slidablel in a track formed by two parallel channels 18 of the so-called Z-bar type, one channel at each side of the opening on the under side of the vehicle floor and longitudinally of the vehicle. 19, in Figs. v2 and 6, is a metal plate which may be secured between the iioor and said channels to Contact with plate 17 and enabling the latter to be ymore easily Amoved in its tracks. 17n is a longitudinal integral extension of plate 17 and has a toothed rack 2O the pitch line of which is preferably on the extended longitudinal center line of plate 17 (see Fig. 3).

I/Vhe'ny plate 17 is in position closing the aperture l5 the outer teeth of rack 2O are engaged by a pinionv21 fixed on a vertical `shaft 22 journaled in a bearing plate 23 secured on the floor 10 adjacent one of the car seats 13. The major part of shaft 22, above bearing 23, is of enlarged diameter and provided with a helical or spiral groove 24 in its outer surface. This groove is engaged by a radial fixed pin 25a (see Figs. 4 and 5) in the lower end of a tubular member 25 terminating in an enlarged head 25b which is normally in accessible location at the side of the car seat. The member 25 is slidable verticallyfin the bore 26 of a bracket 26 fixed as at 27 to a convenient stationary element such as the seat frame 13b of the seat 13. The member 25 has a longitudinal eX- ternal keyway 25c (see Figs.' 4 and 5) slidably engaged by a fixed key 28 (Fig. 5) in the bore ofthe bracket 26 to prevent rotation of member 25.

29 is an L-shaped guide and stop member secured to the under side of the plate eX- tension 17, as at 30 near the plate and 31 at the rear end of the rack. The long arm of this member is parallel to the rack and the short arm serves as a stop against shaft 22 when plate 17 is in a position closing the aperture 15 (see Fig.

In the operation of the device the occupant of the seat merely presses down on the head 25b of the push member 25 and the pin 25'L in the latter moving downwardly also and engaging the spiral groove 24 of shaft 22 causing the latter and its pinion 21 to rotate. The pinion being in mesh with the rack 20 will cause plate 17 to be moved '22. push member down'the spring. is compressed away from the opening l and through which occupants of the vehicle may expectorate or throw any Waste matter outof the vehicle. v

V32 (Fig. 4) is a compression coil spring inserted in the bore of the-tubular pushV member 25, one end ofthe spring being secured as at 32a in the .head 25hpand the-'other end fixed as at 32b in the upper end of shaft Thus when' the operator 2^ presses 1 the into the decreasing space between head b and the upper'end of shaft 22." Thisaction rotates the shaiit'22`,` asfpreviously described, and said rotating action also twists the coils of the spring.
